Electronic Restoration >> How To Restore Smoke Damaged Electronics

When loss of off-the-shelf units does not compromise mission success, a waiver may be granted on a case-by-case basis that exempts the unit from the requirements of this document, subject to written approval of the project. However,additional unit level testing, such as thermal cycling or thermal vacuum testing, How To Restore Smoke Damaged Electronics may be directed by the project in lieu of piece part level screening. 

These tests shall be performed on flight parts in accordance with the requirements of Table 2 of each applicable section. Testing shall be performed on 100% of flight parts (and is implied by character "X”),unless sample testing with acceptable criteria is designated. For example, How To Restore Smoke Damaged Electronics 4(0) designates four test samples, and zero failures of these samples are permitted. 

Screening tests shall be performed in theorder shown unless otherwise indicated. Any test required by screening Table 2 that is alreadyperformed by the procurement specification (military or SCD) or that is normally performed by themanufacturer need not be repeated. However, How To Restore Smoke Damaged Electronics lot specific attributes data must be submitted to showthat tests were performed with acceptable results. 

The user is responsible for specifying and documenting device-unique requirements, if any. Exceptions shall not be permitted unless approved bythe project, and such exceptions shall include a written rationale that describes the proposed application How To Restore Smoke Damaged Electronics and its criticality to the project.6.4 Qualification Tests These tests shall be performed in accordance with the requirements of Table 3 of each part type section.

Qualification tests shall be performed in the order shown unless otherwise indicated. Any test requiredby qualification Table 3 that is already performed by the procurement specification (military or SCD)need not be repeated. However, lot specific or generic attributes data, as applicable, How To Restore Smoke Damaged Electronics must be submittedto show that tests were performed with acceptable results. 

Qualification is generally considereddestructive and How To Restore Smoke Damaged Electronics samples shall be segregated from flight parts. The required sample is indicated by aquantity (reject number) Ex: 4(0) or Lot Tolerance Percent Defective (LTPD). Qualification by usagehistory or similarity to qualified parts may be acceptable as discussed below.

History. A part can be considered qualified if it has been used successfully in (a) applicationsidentical to that proposed (heritage design) or (b) applications different from that proposed if theapplication, including derating and environmental conditions, How To Restore Smoke Damaged Electronics is fully documented and is more severethan the proposed application. 

The part must have been used for 2 years minimum total operating timein orbit. The part must have been built by the same manufacturer in the same facility, How To Restore Smoke Damaged Electronics using the samematerials and processes to an equivalent SCD. It is the user's responsibility to have such evidencedocumented.

Similarity. A part can be considered qualified if it is similar to a part for which qualification test dataexists, How To Restore Smoke Damaged Electronics and the test data (a) satisfies the requirements specified herein for the applicable part level, and(b) is available and is less than 2 years old relative to the lot date code of flight parts. 

In order to beconsidered similar, the part shall be made by the same manufacturer on the same manufacturing line, or on a line with only minor differences, How To Restore Smoke Damaged Electronics and these differences shall be documented and shown to representno increased reliability risk.3. Existing Test Data. Parts can be qualified by existing test data that meets the requirements specified herein when so indicated in Table 3.

Lot specific data indicates that flight parts have the same lotdate code as the qualification samples. Lot specific data is always acceptable in place of qualificationtesting when it meets the requirements specified herein. (b) Generic data is an acceptable basis forqualification if it is less than 1 year old relative to the lot date code of flight parts, How To Restore Smoke Damaged Electronics and is acquired andreviewed for acceptability by the user. 

The user shall also verify that the data is representative of flightparts, e.g., built in the same facility using identical or How To Restore Smoke Damaged Electronics similar processes. Derating shall be performed by the designer in accordance with the requirements set in Table 4 for each category of parts documented in Sections C1 through W1. These derating factors do not precludefurther more stringent derating; for example, to account for radiation induced degradation. 

Developer controlled derating plans may be used upon acceptable review and project approval.6.6 Manufacturer, Distributor and Test Laboratory Assessment6.6.1 Manufacturer. For all part levels, How To Restore Smoke Damaged Electronics the part manufacturer shall be assessed for its ability toproduce parts with consistent quality that meet performance specifications and workmanship criteria, aswell as the capability to deliver parts on schedule. 

A certificate of conformance should be requested fordelivery with each purchase order.6.6.2 Audits. For level 1 and level 2 parts, a site visit to assess the manufacturer's capability insatisfying the requirements specified herein is recommended for unproven manufacturers. The term"unproven” means that there is no successful flight heritage on parts procured from the manufacturer, or How To Restore Smoke Damaged Electronics that the manufacturer has not pursued and qualified their production line for space quality parts.

However, formal audits are not a requirement of this document.6.6.3 Customer Source Inspection (CSI). CSI is not a requirement of this document, but it isrecommended for unproven parts, How To Restore Smoke Damaged Electronics hybrid microcircuits intended for use in level 1 and level 2applications, and for parts from manufacturers with a known history of inconsistent quality. 

CSI is mosteffectively performed at precap visual inspection and at final electrical test and data/traveler review. IfCSI is used as a substitute for required data (i.e., data is reviewed at the manufacturer's facility ratherthen acquired by the user), How To Restore Smoke Damaged Electronics then the CSI shall be fully documented in a trip report that is submitted to the project. 

The report shall summarize the data reviewed How To Restore Smoke Damaged Electronics and reference manufacturer test reports.6.6.4 Distributor. Parts shall be procured from authorized distributors as much as possible with-in thefederal procurement regulations. This minimizes the risk of receiving parts that have been mis-marked or misrepresented or subjected to substandard storage or handling conditions. 

If other distributors areused, they shall be assessed with respect to their ability to provide parts without adversely affecting theirquality and integrity. Storage conditions for components should be evaluated for humidity and How To Restore Smoke Damaged Electronics ESD controls. Humidity control is of particular concern when procuring PEMs. 

Overall distributorassessment is required whether procuring standard military parts or commercial parts.6.6.5 Test Laboratory Assessment. Users shall assess the suitability of the test laboratory chosen toperform any screening and qualification tests on space flight parts. This shall include evaluation of testcapability and quality assurance processes for handling of parts, How To Restore Smoke Damaged Electronics ESD and humidity control, test plandevelopment and implementation, documentation of test results, etc.
